Description

A kind of backrest leg rest electric integrated mechanism and seat
Technical field
The present invention relates to a kind of seat, a kind of backrest leg rest electric integrated mechanism and seat are concretely related to.
Background technique
The market of not busy chair is being quickly grown in recent years, this novel product of leisure chaise longue has gradually come into doing for many people Public room, parlor, among bedroom.From earliest, the best single leisure chaise longue of technology starts, and is particular about the novel of ergonomics till now and stops Not busy chair;User's seat in the case where facing upward state of inclining, which can be lost, from the beginning supports human body waist, that is, we " run about waist " that is commonly called as, To " seat back linkage technique " till now, can accomplish to make user face upward incline during, buttocks is relatively fixed with seat surface.People Enjoy leisure chaise longue provide relaxed position while, the requirement to leisure chaise longue also gradually rises, and consumer has been not content with Traditional leisure chaise longue by adjusting posture either manually or by variation center of gravity, this seems not simple enough and comfortable.
Consumer needs to take chair cushion to a of " more lying fallow ", as long as next purely by touch screen or by piezoelectricity Dynamic button, that is, adjustable backrest and the cry for increasing the Easy chair for packing up foot pad are higher and higher.Therefore, by leisure chaise longue Middle implantation motor becomes leisure chaise longue research and development and improved new direction.
It also occurs through motor in the prior art and realizes control, but it is by two electricity in use Machine faces upward lifting for incline process and leg rest to realize respectively, and such structure occupied space is big, and weight weight is complicated for operation.
Summary of the invention
The purpose of the invention is to overcome two motors in the prior art to operate separately to face upward lifting for incline process and leg rest, It is inconvenient, the deficiencies of weight weight, duty is big, and provide a kind of lift that can be realized by a motor and face upward incline process and leg rest It rises, easy to operate, duty is few, the good backrest leg rest electric integrated mechanism of stability and seat.
The present invention realizes that technical solution used by its first goal of the invention is: a kind of backrest leg rest electric integrated machine Structure, comprising:
Seat frame, realization sit, lean on, the basic components of leg rest function;
Backrest, is arranged in the rear end of seat frame and can be along the back-supported lever of seat frame reclining backward;
Footrest component is arranged in the front end of seat frame and can stretch out forwards expansion along seat frame and fold to the seat frame back lower place The foot of contraction places part;
Oscillating bar assembly, for realizing the rotary swing mechanism of footrest component extension and backrest hypsokinesis, the oscillating bar assembly It is mounted below seat frame, jagged swinging disc is set on the oscillating bar assembly;
Leg rest link assembly connect the telescopic folding for realizing footrest component with footrest component and seat frame respectively;It is described Leg rest link assembly on connect jagged hinge;
Backrest connecting rod component connect the reclining for realizing backrest with backrest and oscillating bar assembly respectively;
Actuator, for driving footrest component and backrest sequentially-operating, the actuator respectively with oscillating bar assembly and put Foot component connects and drives oscillating bar assembly and footrest component relative motion;
Notch hinge cooperation on notch swinging disc and leg rest link assembly on rolling assembly, with oscillating bar assembly, which is realized, puts It the hypsokinesis of the extension retraction of foot component and backrest and before faces upward;
The notch hinge and notch swinging disc is arranged in opposed configuration in rolling assembly two sides, is formed to rolling assembly Rolling extrusion structure.
The backrest leg rest electric integrated mechanism passes through an actuator, a rolling assembly under the premise of retaining high degree of comfort It realizes the sequentially-operating of leg rest link assembly and backrest connecting rod component jointly with an oscillating bar assembly, successively expansion and hypsokinesis, drives Moving part may be implemented finger and manipulate the function of adjusting several movements entirely.In the initial state, leg rest is in and packs up, and backrest is in straight Vertical state, at this point, rolling assembly is tightly attached to the indentation, there of notch swinging disc, the arc surface of notch hinge is pressed against rolling assembly, makes The notch of notch swinging disc must not be detached from by obtaining rolling assembly, to guarantee this of arc surface rolling of the rolling assembly in notch hinge Oscillating bar assembly does not rotate during a;Footrest component is slowly lifted when actuator operation, leg rest connecting rod during lifting Component movement, until leg rest lifts completely.After leg rest lifts completely, actuator is continued to run, due to footrest component at this time It lifts completely, the actuator one end being fixed on footrest component is motionless, so that the actuator other end retreats, oscillating bar assembly is pushed to turn Dynamic, the rotation of oscillating bar assembly is so that backrest connecting rod component rotates, so that seat frame be made to act, backrest falls down.When contraction footrest component With lift by unlucky, structure motion principle and stretching footrest component and topple over that backrest is identical, and process is opposite.User only needs when use The chair back is leaned against, the raising of angle and foot pad that chair is lied down then can be converted by operation button switch and is packed up. And above structure can ideally be installed on the bottom of seat frame, and inner space has not only been efficiently used, and can also increase whole The internal structure stability of body leisure chaise longue, in the case where the stand-by time that can reach abundance and reasonable access times, as far as possible Volume and weight is controlled, had not only been able to satisfy the requirement of consumer, but also overall weight will not be made overweight.
